Technology developed at U ‘blows away’ head lice

SALT LAKE CITY (AP) - When it comes to head lice, there’s an inescapable ick factor.

So when parents are notified of an outbreak at their child’s school or they see them on their child’s head, most rush to the store to buy a fine-toothed comb, specially formulated shampoos or other products designed to eliminate them.

Because head lice reproduce quickly and have evolved to resist treatments, eradicating them can be difficult and time-consuming.

Ashley Hafer, a surgical nurse, says her personal experiences of ridding her twin daughters of head lice were instructive.

“Both of my girls had bugs in their hair. It was the bane of my existence. However, it became a business opportunity,” she told the Deseret News (

Hafer and scientist Rita Skolnick are owners and operators of Hair Maidens professional lice removal service that recently opened a clinic in downtown Salt Lake City. Hair Maidens uses technology that literally blows lice away.

More correctly, the AirAllé medical device blows air warmed to precisely 130 degrees at a specific velocity that dehydrates lice and their eggs.

Hair Maidens first operated as a mobile business. Recently, Hafer and Skolnick opened an office at 231 E. 400 South, Suite 355, which is across the street from the Salt Lake City Main Library. Appointments are available seven days a week.

The AirAllé medical device was developed by University of Utah researchers, led by evolutionary biologist Dale Clayton.

Clayton studies host and parasite interactions, primarily among birds and bird lice. When he moved his lab to the U. from Oxford University 17 years ago, Clayton had difficulty keeping lice alive on birds.

“We discovered it has to do with the arid conditions, and if we would humidify rooms, we could keep cultures of lice alive on birds,” he said.

The research team also discovered the inverse was true: Using dry air could kill lice. About the same time, Clayton’s children got head lice, which opened his eyes to an application for the knowledge beyond keeping birds lice-free for lab experiments.

“This turns out to be a serendipitous, useful thing. If you want to kill lice, you can make it even drier than it is in Utah by blowing warm air across a kid’s head,” Clayton said.

But creating a medical device that can safely and effectively kill head lice and their eggs presented significant challenges. Fortunately, the university has an established track record of supporting research from labs to practical applications in the marketplace.

Clayton’s lab was a Center of Excellence, meaning “the state of Utah spent about a half-million dollars on the research. That helped us figure out the delivery to achieve high kill rates,” Clayton said.
